PROTECTING-TUBE FOB TELE'PHONE-CORD OUTLETS.

Specification of Letters Patent.

Patented Oct. 3, 1916.

Application filed December 22, 1914. Serial No. 878,598.

To all whom it may concern:

Be it known that I, JOHN M. KLUG, a citizen of the United States, residing at Novelty, in the county of Geauga and State of Ohio, have invented certain new and useful Improvements in Protecting-Tubes for Telephone-Cord Outlets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to telephones, and more particularly to an improvement on portable telephones, the primary object of which is the provision of a tube formed upon the protective cap for the outlet of telephone cords, for protecting the latter .from injury or breakage at the outlet of the cord from the protective cap of the receiver or transmitter of the telephone.

In the caps of the present construction, there is only a thin sheet of metal engaging the cord at its outlet, and this tends to cut the insulation from the coil, causing a short circuit and rendering the telephone inoperative, during the handling of the same; and it is an object of this invention to form a tube upon a protective cap which will provide a greater amount of engaging surface with the telephone cord, thereby eliminating the cutting of the cord and increasing the longevity of the telephone.

l/Vith the foregoing and other objects in view, this invention consists in such novel features of construction, and combination of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, and claimed.

In describing the invention in detail, refhad to the accompanying drawings, wherein like characters designate like or corresponding parts throughout the several views, and in which:

Figure 1 is a central sectional view through the improved protecting cap showing the telephone cord in elevation, and Fig. 2 is 'a plan view of the protecting cap and the receiver casing of the telephone.

Referring more particularly to the drawings, 1 designates the casing of a telephone receiver, which has an opening 2 formed therein, for the insertion into the casing of the telephone cord 3. The opening 2 has the reduced end 4 of a collar 5 inserted cap 9 is mounted upon the outer screw threaded surface of the collar 5, the plate 8 is forced downwardly and into abutment with the upper outer end of the collar 5, thus forcing the rubber washer 7 into the bore of the collar and forming a fluid tight connection between the collar 5 and the telephone cord'3.

The cover 9 has a tube 10 formed integral therewith, which tube extends upwardly Or outwardly from the outer end of the cover, tion of the telephone cord 3, so as to prevent the edges of the cover which surround the opening therein, through which the cord 3 passes, from cutting the insulation from the cord and forming a short circuit which incapacitates the telephone. The tube 10 has its outer end rolled as is clearly shown at 11, so as to provide a non-abrading or non-cutting surface for engagement with the telephone cords and to permit of the movement of the telephone cord within the tube without having the cord cut by the sharp edges of the tube. The tube 10 is formed integral with the cover or cap 9, so as to increase the longevity and strength of the device, and in the construction of the cover is spunthereupon as is common in the art of constructing similar caps or closures, of sheet metal.

In reducing the invention to practice, certain minor features of construction may necessitate alterations to which the patentee is entitled provided such alterations are comprehended within the scope of what 1s claimed.

What is claimed is In a device of the character described comprising a collar having a central bore to receive a telephone cord, said collar provided with its lower end reduced and threaded into a telephone receiver or transmitter, the bore of said collar enlarged outwardly and upwardly to provide inclined walls, a resilient wedge shaped washer carried by the telephone cord and resting and is provided for the recepupon the inclined Walls of the collar, a me- Wardly to prevent cutting of said telephone tallic plate mounted upon said Washer, a cap cord. i
